We got one more clear night here. And which winter target can be finished in one night? Right, the Orion Nebula:
See https://www.astrobin.com/qe320u/ for technical details.
Actually I collected some 10 sec shots for the core but didn't notice the thin clouds while imaging. But it worked surprisingly well with the 3 min subs only. Amazing how long you can expose with the 571 sensor and what ST's HDR module can do... And cool to see all that dust already after 5 hrs.
With regard to the ringed stars I noticed here that SVD together with my pretty strong usage of Shrink is the reason. If there are slight dark rings around stars after SVD it gets worse with the Tighten preset. Adjusting the Color tame and the Halo extend parameter helps.

Stefan
